The never list for a Californian rabbit
A Californian rabbit should never be given avocado, chocolate, onion, garlic, leeks, raw potato or potato peelings, rhubarb leaves or stalks, or the pips and stones from apples, cherries, plums, and peaches. Bread, crackers, pasta, breakfast cereal, cake, and biscuits also belong on the never list for a Californian, even though they are not sharply toxic, because starch feeds the wrong gut bacteria in a rabbit. Iceberg lettuce is a poor choice too, being mostly water with little fibre. Nuts and seeds are far too fatty for a rabbit's digestion, however eagerly this big breed may take them.
Why a Californian's size makes scraps riskier, not safer
A Californian's size does not make scraps safer, because the risk sits in the fermentation system, not the body weight. Rabbits are hindgut fermenters, and a Californian's large caecum works best on a slow, constant flow of grass hay fibre. A sudden load of starch or sugar from bread or sweetcorn can shift that fermentation, produce excess gas, and slow gut movement. Because Californians are enthusiastic, food-driven rabbits, they will often eat a harmful item with real enthusiasm, so willingness to eat something tells you nothing about whether it suits them.
Kitchen situations that catch Californian owners out
Californian rabbits most often meet banned foods through ordinary kitchen moments rather than deliberate feeding. A rabbit loose in a kitchen can reach a dropped onion skin, a potato peeling by the bin, or a chocolate wrapper on a low table. Children offering a share of a biscuit or a crisp is another common route, and well-meaning visitors may present a banana or a handful of grapes as a treat. Guard the floor during food preparation, keep fruit stones and pips in a closed bin, and give visitors a short approved list — leafy herbs and a small piece of pepper — before they meet the rabbit.
What a Californian should be eating instead
A Californian's bowl should be boring in the best way: unlimited grass hay available at all times, a daily handful of leafy greens such as romaine, spring greens, coriander, and dandelion leaves from a chemical-free source, plus clean water in a heavy bowl or bottle. Measured pellets suited to a large adult rabbit round the diet out, but hay should always be the bulk. Treats, when they happen, are a small slice of apple without pips, a single strawberry, or a blueberry or two — given occasionally, not as a daily expectation this breed will quickly learn to demand.
If your Californian eats something on the never list
If a Californian rabbit eats avocado, chocolate, onion, or rhubarb, contact a veterinarian promptly rather than waiting for signs, and note what was eaten and roughly how much. For lower-risk items such as bread or iceberg lettuce, push hay, refresh the water, and watch over the next day for a shrinking appetite, smaller or absent droppings, a hunched posture, or teeth grinding, which in a rabbit signals discomfort. A Californian that stops eating altogether needs veterinary attention the same day, because a rabbit gut that stops moving is an emergency in its own right.
